Designed by Lincoln Memorial architect Henry Bacon in 1903 as a summer estate for coal baron William Cutler Atwater, the palatial shingle-style home, originally called Brightwaters (later renamed Kincora by its third owner, attorney Henry L. O’Brien), has been host to many a notable visitor, as well as to a few grand fundraisers in more recent times.

Accessible by a front drive lined with an alee formed by 44 century-old catalpa trees, the property spreads across 6.86 acres with 100-year-old grapevines, formal gardens, a Lord & Burnham greenhouse with potting house, 56-foot waterside gunite pool and spa, tennis, and 620 feet of water frontage with deepwater dock on Quantuck Bay.

The 24-room mansion/manor house includes 9 bedrooms, 9 full and 2 half-baths and 6 fireplaces. A dramatic entryway opens in to the grand center hall foyer, and through to a U-shaped three-story staircase, living room with fireplace and banquet-sized formal dining room with hand-painted dune murals and fireplace. The home has a gourmet kitchen with breakfast area, billiards room, sunroom, second-floor office, sitting room, balconies with mahogany decks, and third-floor living room—all providing the ultimate in luxurious living spaces.

A charming carriage house and separate 4-car garage complete the picture.

Current owner Len Conway bought the Atwater estate from O’Brien around 1990 and proceeded with some tasteful renovations. Conway listed the property for $24,750,000 in 2012, then lowered it to $17.75 million in 2013.
